Can I put aftermarket glass on my busted Bi-Xenon headlights?

So my headlight glass has been shattered on the passenger side. After fainting at the replacement cost of the factory Bi-xenon assembly (over $1000), i'm looking for other options. Of course, Volvo does not sell just the glass. I see that there are some aftermarket glass lenses available from various sources. Aside from the slightly different pattern in the glass, they look like they fit all versions of these headlights, as they just clamp on over the assembly... anyone have any experience with this? Good info has been hard to find on these.
